Interface Not Supported – Windows 7

Windows 7 has been working well, but the other day it just stopped being happy and refused to launch any Explorer windows (like file manager). It said, “Interface Not Supported” and that was it. Come on Microsoft, please be a little better about your errors and give some information. I google’d for a while and found a fix. Re-register all the DLLs. I just pasted the following into the command prompt. All fixed up.

Thanks, i solved my windows problem, i after do it each folder you click on it open in new window and in folder options your chekmark is on open each folder in same window, i think something is changed here, can you help me please?

This didn’t work for me, either. I had the message “Explorer.EXE Interface not supported” with the EXE in capital letters, which is an indicator of a virus in the system. I got rid of it after rebooting in safe mode (push F8 on boot-up) and doing a complete system scan by Avira. It found a virus and deleted it. After that all was good again. HTH.

yay! web site doesn’t work in ie7…already upgraded current computer to ie8…hadn’t yet found ietester…stupidly tried to install ie7 – i know, i have no idea what i was thinking. ran cmd.exe as administrator and pasted it in – explorer started working without even a reboot! excellent!

YEES!!!! THANK YOU!!! I thought i had a virus and i was expecting to have to re-install windows or worse get a new computer, but you my friend have provided an answer i’ve been looking forever for in one short article. THANK YOU SO MUCH!!!! 😀

Tried this and it didn’t work, had to run it as a startup batch script because cmd.exe doesn’t work but it still comes up with “Interface Not Supported” when I try to open anything so I have been forced to create a new user which also isn’t doing very well god I hate windows why must EVERYTHING be so dam difficult?

I found a thread about doing such weird stuff in a batt file. It was about Win98…
I googled a bit more and found that magic command:
FOR /R C: %G IN (*.dll) DO “%systemroot%system32regsvr32.exe” /s “%G”

It took about 2 min and showed up a LOT of errors like ” Runetime error! ”
Just click ok on allll of them.
